throat portions thereof. Such means comprises in general suitable frame members which are preferably adjustable and detachthe flue lining during the bricking operation. The objects of this invention are to provide an improved framework or sup-port which will provide a suitable form for a fireplace smoke chamber or throat section; to provide a form of the character indicated which is constructed of a plurality of sections with means for conveniently connecting the section; to provide a smoke chamber support having reticulated sections or sections having bars for supporting the brickwork and to provide such other improvements in construction and such other advantages as will appear from the following description.

In the accompanying drawing illustrating this invention;

Figure 1 is a front view of a form or frame embodying this invention;

Figure 2 is a plan view showing the front section swung outwardly or in adjusted position;

Figure 3 is a side view; and

Figure 4: is a detail of the rear cross bar or connecting member.

As shown in the drawing a frame or form for the smoke chamber comprises the front section 5 having a longitudinal lower bar or strip 6 with a forwardly projecting flange 7. It also has a longitudinal top bar or strip 8 which is connected at the ends to the lower bar by diagonal end strips 9, these being tapered to give the desired shape to the sides of are also connected by parallel bars 10 thereby forming a substantially rectangular opening at the center of the front frame. The end strips 9 are also connected to the strips orv bars 6 and 10 by diagonal bars 11, as shown the smoke chamber. The top and bottom bars preferably formed integrally-with the sec- "tion and-which provide fastenings for the adjacent frame members.

The end sections 13 of the smoke chamber which are adaptedto engage the di'a'gonal 5b 7 *bars 9, comprise substantially rectangular able for supporting the brick work and also 7 as shown in Figures '2 and 3, these frames being duplicates-'- or interchangeable. These end frames with diagonal bars or cross pieces'l l,

sections have outwardly projecting flanges- 1 5 at their loweredges and lugs or projections 16 'extending beyond the flanges. The front ';positely disposed slots 18 for receiving fasjteningi-lugs or buttonsxl9 on a cross 'barl20..

which extends across the backof. the chamber and 'connects ithe upper ends of the end sections. The upper edges of the barsi9 are :prefe rablyoffset or provided with flanges 21 which fit against'the edges of the endsections V when the front section is swimg inwardly-or Ito. vertical position and which provide sup- :ports for the overlying brick when the-front .gsection is adjusted to an open positionyas v shown in Figures 2 and 3.vv The variousbarstso or-strips 'forming the different sections ;may be madaeither plain or ribbed in ordernto strengthen the same.

In the construction of a fireplace the outer =briokworkisusually placed :in position prior. 35

to finishing the lining or placing the fire brick position. The end sections 13are preferably supported 7 on the common brick by -=means of the projections 16 so that the fire brick may. be placed inside of the commonnoo brick-and. will come flush with the inner surface :of' the smoke chamber. :The front sectionmay be swung outwardly or adjusted, as shown in Figure-,8, with its loweredge resting on the fireplace damper housingl22 ,;or it may be closed against-the side sections if the fireplaceis 'to be of less depth; When in ex tended position, it will be noted that the outer 1 edge of the flange or projection 21 is in alignment with the outer surface of the adjacent they may be conveniently handled and"as-. 'sembled. Furthermore such reticulated or baredsections may bemade sufficiently strong of cast iron metal so that they are not apt to crack either in manufacture or in use. V

Having thus described our invention which, however, we do not wishto limit ourselves .5

-to the exact construction herein shown and described except as specifiedin the following buttons and means at the rear of the end secend sections so that bricks placed on the end sections and extending beyond the same will rest against and be supported by such edge orflange- The chimney lining as indicated at 23 rests on the top of the smoke chamber frame and the end sections arecovered over with bricks up to'such lining, the frame sections serving to support the bricks as they are being ap'- V plied. The opening through the front section 5 provides access to the lower or inner'sul Y faces of the sections so that the nner surfaces may be pointed up or finished in a convenient manner. After this is done thebricks are applied totheouter surface'ofthe front section being supported in part by the flange 7to complete the bricking in of the chimney throat. The open-Work frames provide means for properly supporting the brick and V at the same time are sufficiently light so that claims. 'What we claim is:

1. A frame or support of the character set 1 forth, having end sections with outwardly. projecting lugs at the lower ends thereof, a

front section with tapered ends for receiving the end sections, means for pivotally securing 1 I the front and end sections togetherat the top and a bar for securing the rear portions of the end sections together.

' 2. A smoke chamber frame comprising a front section having an outwardly projecting flange along the bottom thereof and having fastening buttons ateither side thereof, end sections having outwardly extending projections at the bottoms thereof and having means for receiving said fastening buttons, a cross bar having integrally formed fastening tions for engagement with the fastening buttons on said bar. r

3. A smoke chamber construction eomprismg reticulated endsections formed of cast metal and having recesses adjacent to the tops thereof, a front section formed of reticulated cast metal with tapered ends for en-f gagement with the :end sections, studs on the front section-adjacent tothe top for engage- 7 "men with the recessesin the end sections, and 1 w a bar having projections for engagement with the recesses in the end section'sat the back thereof. p 1 T ERIC A.
